Baghdad, Iraq ? A homemade bomb exploded near a U.S. military vehicle, killing one U.S. soldier and wounding another along a supply route northeast of Baghdad, the U.S. Central Command said early today.

The attack occurred at about 5 p.m. Tuesday, the Central Command said on a statement posted on its Web site.

The soldiers were from the U.S. Army’s 3rd Corp Support Command, it said. The wounded soldier was evacuated to a field hospital.

The statement gave no further details and said the soldiers’ names were being withheld pending notification of their families.

It was the first death of a U.S. soldier reported in several days.

Also Tuesday, a car bomb in the northern city of Irbil, killed an Iraqi and wounded six Americans and 41 Iraqis, the military said. The six Americans were Department of Defense personnel, but the military did not say if they were soldiers or civilians.

The wounded included children from nearby houses and Iraqi Kurdish guards. Firefighters battled to put out car fires at the scene of the blast in Irbil, the largest city in Kurdish-controlled northern Iraq.

A Turkish reporter at the scene said by telephone that the blast collapsed the front of the two-story building. He said that most of the injured were from nearby houses.

In other developments, three U.S. soldiers were injured Tuesday when their Humvee hit a mine on the road near Fallujah, west of the capital, witnesses said. The military confirmed the incident but said it had no details.

The 4th Infantry Division, meanwhile, reported a soldier was seriously injured in a mortar attack Monday near Balad, 50 miles north of Baghdad. Division spokeswoman Maj. Josslyn Aberle said she had no other details.

Firefighters on Tuesday put out a pipeline fire in northern Iraq that had been set by saboteurs a day earlier. It was the fifth such attack on the oil delivery system in less than a month. The acts of sabotage have shut the export pipeline to Turkey and are costing the country an estimated $7 million a day.

One Iraqi was killed and dozens of people were wounded, including six U.S. Department of Defense personnel, in Tuesday's blast. A car bombing early today killed one U.S. soldier and injured another, the U.S. Central Commmand said.
